Accounting software legal obligations in Bachs: the practical guide

Accounting software legal obligations in Bachs rests on three pillars: federal law that applies across Switzerland, cantonal deadlines worth knowing, and tools that eliminate re-keying. This guide puts it all in order, fact by fact.

Digitalising accounting software: what actually works

Access for the fiduciary, the auditor and employees is set by roles: view, enter, approve, close. Well-set rights protect the data and speed up collaboration.

The winning pair for accounting software: a single inbox (e-mail, scan, photo) and one simple rule — no document sits more than a few days without a proposed entry.

A well-structured SME chart of accounts

Nearly all Swiss SMEs rely on the standard SME chart of accounts (Sterchi/Käfer): classes 1 (assets) to 9 (closing), with revenue in class 3 and expenses in classes 4 to 6. Using this standard structure makes conversations with your fiduciary, auditor and tax administration far easier.

In an SME in Bachs, the chart of accounts is also a delegation tool: clear posting rules let a non-accountant prepare most entries without error.

QR-bills and friction-free collections

Supplier invoices benefit from the same standard: the QR code is read on receipt, the payment is staged in e-banking with the desired due date, and the expense entry is proposed with the correct VAT. The purchase-payment-posting chain takes three moves.

For the debtors of a business in Bachs, nothing changes on the payer's side: scan the code, confirm, pay. On the accounting software side, everything changes: the collection entry proposes itself, the receivables ledger updates continuously and reminders go out on exact balances.

The Swiss legal frame for accounting software

Responsibility for the books is personal: in an SA, organising the accounting is one of the board's non-transferable duties (art. 716a CO); in a Sàrl, the managing directors carry the same duty. Outsourcing the execution never transfers that underlying responsibility, including for a company based in Bachs.

For accounting software, the classic early mistake remains mixing private and business: a dedicated bank account and documented private withdrawals eliminate half the discussions with the tax office.

Bachs: what changes, what does not

Sole proprietorship, Sàrl or SA in Bachs: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Zurich.

For a business in Bachs, that means VAT returns identical to anywhere in Switzerland, but a tax return and family allowances governed by the canton Zurich.

Frequently asked questions

When is entry in the commercial register mandatory?

A Sàrl and an SA only come into existence with their registration. A sole proprietorship must register from CHF 100,000 of annual revenue; below that, registration stays voluntary but adds credibility and protects the business name. Registration goes through the canton's commercial register office — for Bachs too.

What is simplified bookkeeping and who can use it?

Sole proprietorships and partnerships under CHF 500,000 of revenue may limit themselves to recording income, expenses and assets (art. 957 para. 2 CO). Once over the threshold — or upon founding a Sàrl or an SA — full accounts with balance sheet, income statement and notes become mandatory. The CHF 500,000 threshold is assessed the same way in Bachs.

How long must records related to accounting software be kept?

Ten years from the end of the financial year concerned (art. 958f CO). Electronic retention is permitted if the integrity and readability of the records are guaranteed — a serious digital archive validly replaces paper binders. A business in Bachs can therefore archive fully digitally.

How much does accounting software cost in Bachs?

It depends on document volume, the number of salaries and VAT complexity — no serious figure can be quoted without examining the file. Two levers cut the bill everywhere: digitised, well-filed receipts and software that prepares entries instead of having them re-keyed.
